according to the information of Sohu. com, there are about 4,111 cold storages in Jinxiang, most of which are liquid ammonia refrigeration and about 211 are fluorine refrigeration.

The fluorine refrigeration system means that the refrigerant used in the cold storage is fluorine, and the complexity of the refrigeration pipeline of the cold storage is not as good as that of the ammonia refrigeration cold storage.
